Multiple reservoir apparatus and methods therefor

A combination multiple reservoir and spray gun assembly comprises a multiple reservoir apparatus and a spray gun. The multiple reservoir apparatus comprises a fluid conduit and a plurality of reservoirs. Each one of the plurality of reservoirs is coupled in fluid communication to an interior portion of the fluid conduit and a spray gun is coupled to a fluid output portion of the fluid conduit for dispensing a spray fluid. The combination multiple reservoir and spray gun assembly further comprises at least one valve and the at least one valve facilitates flow of the fluid at a predetermined rate from each one of the plurality of reservoirs to the spray gun. A person manually adjusts the at least one valve and selectively distributes at least one fluid from the plurality of reservoirs to the fluid conduit. Alternatively, a controller automatically adjusts the at least one valve.
